Gears?

Ford Racing, Summit, and many other no-name brands. Any 8.8 inch will fit...
 
8.8 ok, Thanks!

Ok. On ebay there are many 3.73 8.8's but they say 5.0 mustang, ranger, bronco, and others. Does this matter? I wouldnt thank it would but just asking. Dont want to get the wrong ones.
 
No. You're just using the gears. I'd also reccomend installing a trac-loc unit with the new gears so you get traction on both tires instead of just one. Towncar should be a 28 spline unit.

Would I have to worry any about my tranny or driveshaft?

You should get a shift kit and tranny cooler to protect the tranny. If you experience shaking because of the driveshaft, you can always swap the mmx from a Police Interceptor, which is better rated for speed and vibration...

Im sorry to bother but, what is a "MMX" and what kind of shift kit?
 
Metal matrix composite. It's an aluminum product and is very lightweight...
 
Buy from someone who will guarantee them. Beware of ebay! Summit has an excellent rep as does Ford Racing.

And AMMC or Aluminum p71 driveshaft won't work on a Town Car, it is 3" too short.


Also, the AMMC was only equipped for 2000 CVPIs, which like all 95+ used the 4r70w (and in later years it's successors) which uses a different spline count on trans yoke and will not work in his '91s AOD transmission.
 
The gear set is a M-4209-F373N and has a list of 179.95 and LVC is $144.00, the install kit is a M-4210-C includes all brgs and seals for a list of 120.00 and LVC at $102.00 the trac loc unit is a M-4204-F288 and lists for $215.00 and LVC $192.00.

Oh, I just noticed I made a slight mistake.
The spline count is the same as 95+, it's the outer diameter of the yoke that is different.
 
My gas is free so that is not my concern. I don't want to put in 3.55's and be disappointed when 3.73's are really the way to go. I do not want to replace the driveshaft though.
 
I have been thinking of switching out the gears on my Town Car as well. How much of a gas mileage loss will be seen when going to 3:73 or going a bit lighter to 3:55's from the 2:9 or 3:1 or whatever is in there right now. And with the trac-loc mentioned earlier will that give me the ability to do a burnout with both rear tires instead of one, assuming that 210hp is enough to do so with twice that traction, but I think it will because 1 tire breaks so quickly with a brake stand. Anyways so any answers would be greatly appreciated. Oh, and the shift kit is good, but is the tranny cooler needed? My buddy just put a shift kit on his auto mustang and it really kicks now but he didn't do any tranny cooling stuff just had it flushed when they did the kit install.
 
i want to do the same here 3.73 gears and trac loc and shift kit but im clueless about the shift kit. and what spline axles are on a 95 tc???
